The aim is to use this manipulator to position an optic fiber in front of a laser diode (when the maximum output is passing down the fiber), the fiber is then glued in position. This is how pig-tailed laser diode modules are created.
Industrially the assembly of pig-tail modules uses machines that must cost tens of thousands of dollars. These use the same layout, a Gough-Stewart platform, using six actuators to give the six degrees of freedom control.
in my case the manipulator will be manually moved so that the fiber is within a millimeter or less of the correct position and then the manipulator will make the final positioning and hold the position whilst the fiber is glued down to a support structure.
Other possible uses:
As a platform for supporting small samples in bio-sciences research, either inverted as a standard stage or with a modified main frame to allow the microscope to view down through the centre.
As a manipulator where both triangular frames are modified to allow view down through both parts, with end effector positioned into the centre of the platform.
With an alternate design of platform incorporating vacuum nozzle, discrete optical elements could be manipulated as required.
To support end of microscope fibre optic bundle to allow viewing around a specimen
